In case there is any confusion, let’s set the record straight: duck hunting with unprotected ears causes hearing loss. As hearing doctors at TETRA, we see what years of waterfowl hunting does to our patients. Recent studies show that people with hearing loss are more likely to develop dementia, Alzheimers and other chronic health problems.* Hearing loss impacts overall health and wellness, and ruins the hunting experience.

So why do 86% of hunters NOT use hearing protection? Previous products have distorted the sound of the call, either over-amplified everything or blocked out your surroundings, and simply just weren’t comfortable. We solved those problems with the TETRA Shield Series. Using our patent-pending Specialized Target Optimization™ (STO) voices and calling are clear and natural while AlphaShield Compression reduces loud sounds to safe levels.

Our custom products provide the most personalized fit and protection available.

TETRA isn’t just hearing protection, it’s hearing perfection.

Our Technology

Specialized Target Optimization
Our hearing devices feature patent pending Specialized Target Optimization™ (STO). STO is the world’s first hearing technology that isolates and enhances the exact frequencies needed to improve hearing for your specific hunting environment. With STO, voices are clear, calling sounds natural, wood duck squeals, whistling wings, and mallard drakes are all easily audible.

TETRA products instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer full protection at the very moment it’s needed. For more sustained loud inputs, like loud calling, AlphaShield Compression™ limits the overall output to a safe level, then returns to normal amplification once the loud input has stopped. Never miss a sound you want to hear, and protect your hearing for life.

ClearComm™  is our proprietary algorithm that accentuates human speech while minimizing noises and distractions that occur outside of the frequency range of human voices. ClearComm is useful for better understanding speech and whispers of hunting partners, hearing speech on the range, as well as in other daily activities that require better hearing.

Hearing and the Brain

Research at Johns Hopkins University suggests that more hearing loss increases the risk of dementia. In one study, people with hearing loss were 24% more likely to have Alzheimer’s.* 

With hearing loss, our brains have to work much harder to make sense of what is being said, and even harder to filter out speech from unwanted background noise. Simply trying to understand conversations requires more mental energy and concentration. 

If basic conversations take up most of our mental energy, there is less opportunity for our brains to sort out and store other information. 

At TETRA, our goal is to minimize hearing loss for hunters and shooters, because research shows if we reduce hearing loss, we can also reduce the chance of getting dementia and Alzheimer’s.

Scouting for Turkeys

I have been wearing them around the house to get used to them for the last couple of days. This morning I put them in while scouting for turkeys. I heard two . No back ground noise and I could hear the gobblers clearly. I was able to determine direction of the birds . I have been having a hard time with determining directions of the gobbler. First experience was very positive. Can’t wait to try them again on On opening day.

Best Customer Service!!!

Fist of all, working with this crew to be able to understand what you are looking at. Making a very large purchase like this I wanted to make sure I was going to get a quality product that would do exactly what I needed them to do. They sat down with and and walked me through the process, got me fitted and had my custom order within 10 days. Awesome communication through the whole process. Super excited to put them to use and work with the again in the future!!!

Glad I pulled the Trigger!

Honestly I never do product reviews, but in this case I’m happy to do so. I had looked at the Tetras at hunting shows and online reviews for over a year but just couldn’t get myself to spend that much money. It was only after getting my bell rung from a friend of mine next to me in the blind that I realized I needed to do something to save what was left of my 55 year old hearing. So last season I bought the standard set and loved them right out of the box. Then my friend tried them and loved them so much he bought bought them from me and I turned around and bought the Custom pair. And since I shoot all year around, these have been one of the best investments that I have made for safety and protection. Incredible product, service and staff! I highly recommend Tetra!

Tetra Waterfowl Custom

I haven’t used them on the water yet for hunting. I have used them on sporting clays course and they are great! Perfect fit and finish! I didn’t realize they would have 4 modes. The clear voice works well on the course. Thanks
